Answer:

Step-by-step explanation:

PEMDAS is Parentheses, Exponent, Multiplication, Addition, Subtraction

This is just the order you do the operations.

First, Parentheses.

Second, Exponents,

Third, Multiplication or Division

Last, Addition or Subtraction

So we have,

[6(20) + 3(15)] ÷ 5

We first look at Parentheses.

The first case is 6(20)

6(20) = 120

We have [120 + 3(15)]÷ 5

We solve 3(15) as its the next parentheses

3(15) = 45

We have [120 + 45] ÷ 5

Then we solve for [120 + 45] as it's in brackets.

[165] ÷ 5 = 31

The answer is 31.

Answer:

[tex]\displaystyle (f\circ g)(-1) = 5[/tex]

Step-by-step explanation:

We are given the two functions:
[tex]\displaystyle f(x) = 2x + 3\text{ and } g(x) = -3x - 2[/tex]

And we want to find:
[tex]\displaystyle (f\circ g)(-1)[/tex]

Recall that this is equivalent to:
[tex]\displaystyle (f\circ g)(-1) = f(g(-1))[/tex]

Hence, find g(-1):
[tex]\displaystyle \begin{aligned} g(x) & = -3x - 2\\ \\ g(-1) & = -3(-1) - 2\\ \\ & = (3) - 2 \\ \\ & = 1 \end{aligned}[/tex]

Substitute:
[tex]\displaystyle f(g(-1)) = f(1)[/tex]

Find f(1):

[tex]\displaystyle \begin{aligned} f(x) & = 2x+ 3 \\ \\ f(1) & = 2(1) + 3 \\ \\ & = 5\end{aligned}[/tex]

In conclusion:
[tex]\displaystyle (f\circ g)(-1) = 5[/tex]

[tex]\large\boxed{\tt x^{\circ}= 90^{\circ}}[/tex]

Step-by-step explanation:

[tex]\textsf{We are asked to find the value of x.}[/tex]

[tex]\textsf{The value of x is an angle for this triangle.}[/tex]

[tex]\textsf{Note that we are given 2 other angles, we can use what is given to us to solve for x.}[/tex]

[tex]\large\underline{\textsf{What is a Triangle?}}[/tex]

[tex]\textsf{A Triangle is a shape with 3 sides, and 3 angles. Sometimes these can be congruent,}[/tex]

[tex]\textsf{other times, and most of the time they're not. These are called Equilateral}[/tex]

[tex]\textsf{Triangles. Every Triangle consists of 3 angles that add up to 180}^{\circ}. \ \textsf{If the angles}[/tex]

[tex]\textsf{don't add up to 180}^{\circ}, \ \textsf{then the shape is not a triangle.}[/tex]

[tex]\textsf{Now that we know a Triangle has 3 angles that add up to 180}^{\circ}, \ \textsf{we can create an}[/tex]

[tex]\large\underline{\textsf{Solving;}}[/tex]

[tex]\textsf{All 3 angles add up to 180}^{\circ}, \ \textsf{let's create an equation.}[/tex]

[tex]\tt 180^{\circ} = 37^{\circ} + 53^{\circ} + x^{\circ}[/tex]

[tex]\textsf{To make x the subject, move x to the other side of the equation by subtracting x.}[/tex]

[tex]\tt 180^{\circ} - x^{\circ}= 37^{\circ} + 53^{\circ} + x^{\circ} - x^{\circ}[/tex]

[tex]\textsf{We should also move 180}^{\circ} \ \textsf{to the other side of the equation as well.}[/tex]

[tex]\tt 180^{\circ} - 180^{\circ} - x^{\circ}= 37^{\circ} + 53^{\circ} -180^{\circ}[/tex]

[tex]\underline{\textsf{We should have;}}[/tex]

[tex]\tt- x^{\circ}= -180^{\circ} + 37^{\circ} + 53^{\circ}[/tex]

[tex]\textsf{We should remove the negative for x by dividing the whole equation by -1.}[/tex]

[tex]\frac{\tt- x^{\circ}= -180^{\circ} + 37^{\circ} + 53^{\circ}}{-1} \rightarrow \tt x^{\circ}= 180^{\circ} - 37^{\circ} - 53^{\circ}[/tex]

Answer:

7.722[tex]cm^2[/tex]

Step-by-step explanation:

Work out the area of the circle

By the length of the square, you know the diameter of the circle is 12 cm so the radius is 6cm. Then you can calculate the area of the circle by doing

[tex]6^{2}[/tex]π =36π [tex]cm^{2}[/tex]

Work out the area of the square

12 x 12 = 144 [tex]cm^{2}[/tex]

So the bit not occupied by the circle will be 144- 36π = 30.888 [tex]cm^2[/tex]

However, the shaded area is just 1/4 of this bit so 30.888 / 4 = 7.722 [tex]cm^2[/tex]

Answer:

180° = pi radians

Step-by-step explanation:

360° = 2pi radians

90° = pi/2 radians

see image

180° is pi radians.

pi radians is equivalent to 180 degrees, option B is correct.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The radian equivalent of 180° is pi radians.

This is because a full circle is 360°, which is equivalent to 2 pi radians. Therefore, half of a circle or an angle of 180° is equivalent to half of 2 pi radians, which is pi radians.

Hence,  pi radians is equivalent to 180 degrees, option B is correct.

Answer:

Step-by-step explanation:

7(x + 2) = 91

Distribute the 7 over the parentheses:

7x + 14 = 91

Subtract 14 from both sides of the equation:

7x = 91 - 14

7x = 77

x = 77/7 = 11.

Answer:

X=11

Step-by-step explanation:

[tex]7\left(x+2\right)=91[/tex]

Divide both sides by 7:

[tex]\frac{7\left(x+2\right)}{7}=\frac{91}{7}[/tex]

Simplify:

The price of the advance ticket is  $40 and the price of the same day tickets is $30.

a + b = $70 equation 1

20a + 35b = 1850 equation 2

Where:

a = cost of one advance ticket

b = cost of one same day ticket

Multiply equation 1 by 20

20a + 20b = 1400 equation 3

Subtract equation 3 from equation 2

15b = 450

Divide both sides by 15

b = $30

Subtract $30 from $70.

$70 - $30 = $40

3 and 27

Step-by-step explanation:

Step 1:  Determine which two terms we can use

We have the following numbers to choose from:  3, 14, 27

Adding two numbers to get a multiple of ten means that the number that we come up with needs to be divisible by ten.  For example:  20, 30, 50, 100 are all multiples of ten.

In this example the only one that would add up to create a multiple of ten is 27 and 3 which would give us 30 which is a multiple of 10.

A bran with the dimensions shown is to be painted. One gallon of pain covers 400 square feet. 23 gallons of  pain is need for the one coat of the barn. Option B is correct.

Given that,

A bran with the dimensions shown is to be painted.

One gallon of pain covers 400 square feet.

We have to find how much gallon of paint for one coat on the entire external of the bran, including the roof.

So,

We can see in the picture

1 side of the barn is rectangle with length and breath that is 24 feet and 60 feet.

1 side of the barn is square with side 40 feet.

The front upper side has a triangle with height 21 feet.

Now, We find the area of the rectangle.

Area of rectangle is length × breath

=24feet×60 feet  

=1440 square feet

1440 square feet divided by 400 square feet

1440/400=3.6

So, the bran has 2 rectangular sides so 3.6+3.6=7.2

Now, we find the area of square.

Area of square is side × side

=40 feet ×40 feet

=1600 square feet

1600 square feet divided by 400 square feet.

1600/400=4

So, the barn has 2 square side so 4+4=8

Now, we find the area of triangle.

Area of triangle is 1/2×breath ×height.

=1/2×40 feet×21 feet

=1/2×840 square feet

=420 square feet

420 square feet divided by 400 square feet.

420/400=1.05

So, the barn has 2 triangles back and front so 1.05+1.05=2.1

Now, we find the area of roof

Roof is in rectangle with breath 60 feet and height 21 feet

Area of rectangle is length × breath

=60 feet ×21 feet

=1260 square feet

1260 square feet divided by 400 square feet.

1260/400=3.15

So, the barn has 2 rectangle roof so 3.15+3.15=6.3

Now, Adding all the areas we get

=7.2+8+2.1+6.3

=23.6

Therefore, approximately 23 gallons of  pain is need for the one coat of the barn. Option B is correct.
